make sure that you have enter the IAC's Driver Name right. exactly Like this:
Device Name: "IAC Driver"
Ports: "Spark1 Midi OUT"
if you have already a remote Controller in use in Logic (maybe with iPad or something else) then you have to remove it.
hope it helps, because i had the same issue,
And for the Envoirement Window, i see that you need to make one more connection.
1-Make a (new Instrument).
2-by click on the (new Instrument) you will see some Parameter on the left side.
3-Port must be set (Off)
